Poly B replacement permits in Toronto
What Toronto actually publishes about permitting a residential repipe, verified August 6, 2026.
Is a permit required?
Yes. Toronto's permit-required list includes installing or modifying plumbing systems, with only fixture repair and replacement exempt, and the city issues stand-alone plumbing permits for work not tied to other construction. A repipe modifies the plumbing system.
Who can pull the permit
Applications use the provincial permit form, and homeowners can apply for work on their own house, with an exemption from the designer information requirement for owner-applicants. Confirm applicant details with Toronto Building.
Inspections
Mandatory inspections, requested and managed online. Your permit lists the required stages; the city doesn't publish a generic plumbing stage list.
Fees
The published schedule prices buried plumbing and drainage replacement at about $215 flat for a single-family dwelling; the fee for an interior whole-home repipe under a stand-alone permit isn't published separately, so confirm with Toronto Building.
Timelines
No published processing timeline for plumbing permits; Ontario's provincial standard for house permits is ten business days once an application is complete.
Who administers it
Toronto Building; stand-alone plumbing permits can be applied for through Toronto Building Online Services.
What Toronto doesn’t publish
In keeping with this site’s rule of never guessing, these details were not verifiable from Toronto’s published materials and should be confirmed directly with the municipality:
- ?Exact fee for an interior repipe stand-alone permit.
- ?Plumbing inspection stage list.
- ?Processing timeline.
How this fits the bigger job
The permit and inspection record is part of the documentation package your insurer will want after a repipe, alongside the completion certificate. The insurance chapter covers that package, and the cost guide covers what the whole job runs. The Toronto city profile shows how much of the local housing stock sits in the Poly B era.
